Description
The Strike Industries Carbine Flatwire Spring is an affordable and effective upgrade for any AR system utilizing a carbine buffer. Engineered for enhanced performance, this flatwire spring increases the platform’s service life, reduces system vibration, and improves shooting smoothness. Made from cryo-cycled 17-7 PH steel, it offers increased bolt load and decreased compression force, resulting in more reliable cycling and reduced “twang.” Whether replacing a worn buffer spring or completing a new build, the SI Flatwire Spring is a durable, performance-driven solution.
